Select-option dialog not display after click

Hi experts,

i am debugging one program, whitch call subscreen with couple of select-option fields after click on pushbutton on the object oriented ALV. But, when i click on the button of any select-option field (in the subscreen), nothing will happen. I need to display multiple selection screen for a field i clicked on.

I read that subscreen cant call another screen. Is it my case ?

Do you have any idea ?
